VINSON, OF MAYFIELD, KENTUCKY.

CLEVIS.

SPECIFICATION forming part of Letters Patent No. 366,140, dated July 5,1887.

Application filed May 4, 1887. Serial No. 237,148. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. VINSON, of Mayfield, in the county ofGraves and State of Kentucky, have invented a new and useful Improvementin Glevises, of which the following is a specification.

My invention is an improved clevis; and it consists in certainconstructions and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the drawings, Figurel is a side elevation of my invention as in use,the beam being shown in section. Fig. 2is aperspective View of theclevis detached from the beam, and Fig. 3 is a detail sectionillustrating the drafthook and the-front clevis-bar.

The clevis comprises two sections, A and B, the former of which, forconvenience of reference, I term the main. section, while the othersection may be termed the supplemental plate or section. The mainsection A comprises the side plate, 0, and the front bar, D, formed apart of and arranged at right angles to the side plate, 0, the frecendoreX- trelnity of said front bar, D,bcing threaded at The side plate, 0,has near its rear end a threaded opening, 2, for the wrench bolt E, andis provided in advance of said opening 2 with an opening, 3, for thefastening bolt or pin F. The sections A B, it will be seen, areconnected at their forward ends by the arm D of the plate 0 screwinginto the supplemental section, and at their rear ends by the bolt E. Bythis eonslruetiomit will be seen, the clevis may be quickly adjusted tobeams of different thicknesses; and this, too, is attained withoutnecessitating the bending of plates 13 0 toward or from each other, and

without necessitating the front bar being formed separate from both thesaid plates l3 0. Thus I form the clevis-frame B G D in but twopieees,simplifying the construction and reducing the liability of losingany of the parts. The top plate has at its rear end an opening, 4, forthe wrench-bolt, a hole, 5, between its ends for the fastening-bolt F,and a threaded opening, 6, is provided near its forward end for the endof the front bar or arm, D. The

arm D is formed non-circular in cross section, having an eccentricportion or wing, d, extended preferably to the rear, as shown. In

such eccentric wing I form notches d, the arm on a cross-section drawnthrough sa1d notches being approximately circular, as shown. The

draft-hook G has an opening, 9, formed with an extension or wing,corresponding to the eccentric wing of the arm D. WVhen the hook isturned with its opening 9 in full register with the arm Dand the wingsthereof, as shown in dotted lines, Fig. 3, it may be adjusted along saidarm to bring the draft-hook at any suitable height to regulate the depthof the plow. I IV hen at the proper height,the drafthook may be turnedforward to the position shown in full lines, Fig. 3,when the team may behitched. It will be seen that to effect an adj ustment of the draft-hookup or down it is only necessary to remove the bolt F and turn the clevison bolt E, as a pivot, to one side, when the hook may be turned and.adjusted up or down, as desired, and when properly adjusted the clevismay be turned back into line with the beam and the bolt F be reapplied.It will be noticed that the draft-hook cannot be lost unless thesupplemental plate be removed, nor even then unless the said hook shouldbe adjusted immediately under such supplemental plate. IVhile the partG, for convenience of reference, is termed a draft-hook, it is manifestthat it is not of necessity provided with a hook proper, but might beotherwise suitably constructed to facilitate the connection of the teamor other motive power.

Having thus described my invention, what I claim as new is- 1. A cleviscomprising a main section formed with a base-plate and an. arm or front.

bar extended perpendicularly from the forward end of said base-plate andhaving its free end threaded, and the supplementalplate having anopening fitted to receive the end of said arm, substantially as setforth.

2. The improved clevis herein described, consisting of the section A,having plate 0 andarm D, extended at right angle from the forward end ofplate 0, and having an eccentric wing, (Z, and notches cl therein, andhaving its point 1 threaded,the plate B, having an opening to receivethe'poiut l, and the necessary retainingbolts, substantially as setforth.

3. A clevis, substantially as described, comprising a main sectionformed with a baseplate and an arm, connected rigidly with such plate atone end thereof and adapted for engagement by the draft-hook, andthe'supplemental plate having an opening for the free end of the arm,substantially as set forth.

4. The elevis herein described,e0mprising the section 0, having arln D,formed'with a ring, d, having notches d, and with threaded point 1, thedraft-hook G, havingopening g, 10 formed with extension g, the plate B,having opening 6 for point 1, and the bolts E and F, substantially asset forth.
